Ultralight Aircraft
Ultralight aviation (called microlight aviation in some countries) is the flying of lightweight, 1- or 2-seat fixed-wing aircraft. Some countries differentiate between weight-shift control and conventional three-axis control aircraft with ailerons, elevator and rudder, calling the former "microlight" and the latter "ultralight". During the late 1970s and early 1980s, mostly stimulated by the hang gliding movement, many people sought affordable powered flight. As a result, many aviation authorities set up definitions of lightweight, slow-flying aeroplanes that could be subject to minimum regulations. The resulting aeroplanes are commonly called "ultralight aircraft" or "microlights", although the weight and speed limits differ from country to country. In Europe, the sporting (FAI) definition limits the maximum stalling speed to and the maximum take-off weight to , or if a ballistic parachute is installed. The definition means that the aircraft has a slow landing speed and short ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parma Technik Aircraft Engines
Parma (; egl, Pärma, ) is a city in the northern Italian region of Emilia-Romagna known for its architecture, music, art, prosciutto (ham), cheese and surrounding countryside. With a population of 198,292 inhabitants, Parma is the second most populous city in Emilia-Romagna after Bologna, the region's capital. The city is home to the University of Parma, one of the oldest universities in the world. Parma is divided into two parts by the stream of the same name. The district on the far side of the river is ''Oltretorrente''. Parma's Etruscan name was adapted by Romans to describe the round shield called '' Parma''. The Italian poet Attilio Bertolucci (born in a hamlet in the countryside) wrote: "As a capital city it had to have a river. As a little capital it received a stream, which is often dry", with reference to the time when the city was capital of the independent Duchy of Parma. History Prehistory Parma was already a built-up area in the Bronze Age. In the c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Compression Ratio
The compression ratio is the ratio between the volume of the cylinder and combustion chamber in an internal combustion engine at their maximum and minimum values. A fundamental specification for such engines, it is measured two ways: the static compression ratio, calculated based on the relative volumes of the combustion chamber and the cylinder when the piston is at the bottom of its stroke, and the volume of the combustion chamber when the piston is at the top of its stroke. The dynamic compression ratio is a more advanced calculation which also takes into account gasses entering and exiting the cylinder during the compression phase. Effect and typical ratios A high compression ratio is desirable because it allows an engine to extract more mechanical energy from a given mass of air–fuel mixture due to its higher thermal efficiency. This occurs because internal combustion engines are heat engines, and higher compression ratios permit the same combustion temperature to ...

Ignition Magneto
An ignition magneto, or high-tension magneto, is a magneto that provides current for the ignition system of a spark-ignition engine, such as a petrol engine. It produces pulses of high voltage for the spark plugs. The older term ''tension'' means ''voltage''. The use of ignition magnetos is now confined mainly to engines where there is no other available electrical supply, for example in lawnmowers and chainsaws. It is also widely used in aviation piston engines even though an electrical supply is usually available. In this case, the magneto's self-powered operation is considered to offer increased reliability; in theory, the magneto should continue operation as long as the engine is turning. History Firing the gap of a spark plug, particularly in the combustion chamber of a high-compression engine, requires a greater voltage (or ''higher tension'') than can be achieved by a simple magneto. The ''high-tension magneto'' combines an alternating current magneto generator a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inline Engine (aeronautics)
In aviation, an inline engine is a reciprocating engine with banks of cylinders, one behind another, rather than rows of cylinders, with each bank having any number of cylinders, although more than six is uncommon. The major reciprocating-engine alternative configuration is the radial engine, where the cylinders are placed in a circular or "star" arrangement. The term "inline" is used somewhat differently for aircraft engines than automotive engines. For automotive engines, the term ‘inline’ refers only to straight engines (those with a single bank of cylinders). But for aircraft, ‘inline’ can also refer to engines which are not of the straight configuration, such as V, H, or horizontally opposed. Inline engine configurations ;Straight: Engines with a single bank of cylinders which can be arranged at any angle but typically upright or inverted, (e.g. upright ADC Cirrus, inverted de Havilland Gipsy Major). ; V:Engines with two banks of cylinders with less than 180° betwe ...

Four-stroke
A four-stroke (also four-cycle) engine is an internal combustion (IC) engine in which the piston completes four separate strokes while turning the crankshaft. A stroke refers to the full travel of the piston along the cylinder, in either direction. The four separate strokes are termed: #Intake: Also known as induction or suction. This stroke of the piston begins at top dead center (T.D.C.) and ends at bottom dead center (B.D.C.). In this stroke the intake valve must be in the open position while the piston pulls an air-fuel mixture into the cylinder by producing vacuum pressure into the cylinder through its downward motion. The piston is moving down as air is being sucked in by the downward motion against the piston. #Compression: This stroke begins at B.D.C, or just at the end of the suction stroke, and ends at T.D.C. In this stroke the piston compresses the air-fuel mixture in preparation for ignition during the power stroke (below). Both the intake and exhaust valves are close ...

Luhačovice
Luhačovice (; german: Luhatschowitz) is a spa town in Zlín District in the Zlín Region of the Czech Republic. It has about 5,000 inhabitants. It is known for the largest spa in Moravia. The town centre with the spa infrastructure is well preserved and is protected by law as an urban monument zone. Administrative parts Villages of Kladná Žilín, Polichno and Řetechov are administrative parts of Luhačovice. Polichno and Řetechov form two exclaves of the municipal territory. Etymology The name was probably derived from an old personal name Luhač. The name could also be derived from ''luhy'', which means meadows on wetter soil. Geography Luhačovice is located about south of Zlín. The town occupies the valley of the Luhačovický stream with an elevation of about 250 m above sea level, surrounded by a hilly landscape. The entire municipal territory lies in the Vizovice Highlands, however, the eastern part of the territory extends into the White Carpathians Protected La ...

Walter Mikron
The Walter Mikron is a four-cylinder, air-cooled, inverted straight engine for aircraft. Development Developed in Czechoslovakia in the early 1930s, the engine saw limited use in late 1930s and early 1950s. In the 1980s an initial batch of engines was rebuilt by Aerotechnik Moravska Trebova for use on L-13 Vivat motorgliders. Production of new engines followed. The company Aerotechnik was later bought by Parma Technik and production resumed in 1999, under a new name, in the same factory. The engine is mostly used on ultralight, LSA and experimental aircraft. The production is about 20-30 engines annually.
